Frankie Dettori’s long-time friend and former agent Ray Cochrane rates Golden Horn’s 2015 Prix de l’Arc de Triomphe victory as one of the Italian’s finest moments in the saddle.

Dettori will bring the curtain down on his European career at Ascot on Saturday, with the rider having last week officially abandoned his plan to retire from the saddle in favour of a move to America in the new year following a series high-profile international engagements before the end of 2023.

While Champions Day does not put a full stop on his riding career, Dettori’s final afternoon at Ascot promises to be an emotional affair with many of the jockey’s career highlights having taken place at the Berkshire venue.

He memorably went through the seven-race card at the track in September 1996, while his Royal Ascot victories are too numerous to mention, with Courage Mon Ami’s Gold Cup triumph back in June raising the roof.

However, Cochrane, who was Dettori’s agent for 20 years, felt the rider’s renewed association with trainer John Gosden in 2015 provided the most sparkling of moments as he really kicked off what was to be a glorious autumn of his career.

Cochrane told Betdaq: “We had an unbelievable time, with the big winners he rode, but the one that sticks out is Golden Horn.

“He rang me when I was skiing in Switzerland and said, ‘William Buick has gone to Godolphin’. Immediately I said, ‘Have you rung John Gosden?’, and he said, ‘No’, but I could hear him laughing and then he said, ‘I didn’t need to ring him, he rang me’. I remember saying, ‘Get in there!’. At the time, when Frankie had no job, this was like someone putting a big arm around him.

“He started riding well for John and he rang me one spring morning, and said, ‘Ray, we’ve got one’, but he couldn’t remember his name! I kept asking what his name was and a week later he told me it was a horse called Golden Horn.

“Of course, he went on to win the Derby in his first season back with John, but the race that really sticks out is the Arc de Triomphe.

“He was drawn way out on the outside, which for most riders would be a bad draw. I rang him about it, and he said ‘It’s not too bad – this horse is a big lump and can miss the start, so if he was drawn down on the inside I’ll be shuffled back and my race would be over. At least on the outside, I can slot in wherever I want to. That’s the plan’.

“He told me that he was going to keep wide and go straight up the track for seven furlongs, and when he got to the top of the hill he would shift across and move in behind the pacemaker.

“That’s exactly what he did and it was beautiful to watch. He came into the straight on the bridle, gave him a kick and the rest is history.”

The pair first crossed paths when both were working for trainer Luca Cumani in Newmarket and Cochrane became Dettori’s agent in the aftermath of a tragic plane crash in 2000.

Dettori’s life was saved by Cochrane following an accident in which pilot Patrick Mackey died after their plane caught fire just after take-off on a journey from Newmarket to Goodwood.

Cochrane managed to pull Dettori from the wreckage of the aircraft, receiving the Queen’s Commendation for Bravery in 2002 as a result of his actions, but he was forced to retire from racing five months after the incident due to back problems following a series of falls.

He well remembers the day of Dettori’s ‘Magnificent Seven’ though, with Fujiyama Crest’s all-the-way win off top weight in the closing two-mile handicap an experience he is unlikely to forget.

“He’d won the first six races, and by this time he wasn’t walking, he was floating out for his final ride. I followed him out to the paddock and the crowd were all over him,” recalled Cochrane.

“He was drawn on my outside at the two-mile start, and he jumped out and let this horse rip down the outside. We were going flat out down the back at Ascot, we went by the mile-and-a-half start and I heard this roar. There’s a road by the side of the track down the back and I thought it sounded like a tank coming up the side of the road.

“As we were coming out of Swinley Bottom, Frankie was about four lengths clear, and this roar just got louder and I thought, ‘That’s the crowd roaring him on’.

“As we turned into the straight, the noise was unbelievable. It’s the only time in my career that I’ve ever heard the crowd roaring from a mile and a half out. He went on to win of course. It was an unbelievable day and a race I’ll never forget.”

Cochrane also said he has no doubt Dettori will be seen in Britain next year.

“Don’t be thinking that he won’t be back here, he’ll be back at the drop of a hat to ride in all the big races, because that’s what he does. Don’t be expecting this is the last year we’ll see him – I’m sure we can’t get rid of him that quick!

“I’d imagine he’ll be here for the Guineas, the Oaks, the Derby, Royal Ascot, the King George and every other big race he can get a good ride in. I would imagine that John Gosden will call on him regularly, as more than likely will Ralph Beckett if they need a top-class jockey. I imagine he’ll be the first port of call.”

Frankie Dettori credits the Betfred Derby with giving him the “biggest thrill” of his career as he prepares for one last roll of the dice at Epsom.

The Italian is one of the most successful and well-known jockeys of all time, but all good things must come to an end and this year will be his last before retirement.

As a result of that decision, his journey throughout the fixtures of the Flat season is naturally grabbing the headlines, and on Saturday all eyes will be on his ride in one of the oldest and most prestigious races in existence.

Dettori will partner John and Thady Gosden’s Arrest, a Frankel colt with a live chance of providing him with a third victory in the premier Classic.

Those two prior successes and the promise of retirement leave the 52-year-old rider feeling relaxed ahead of his final Derby performance – an emotion he was not familiar with when striving to get his name on the roll of honour in years gone by.

Dettori’s first Derby ride was Pollen Count in 1992, who finished 16th of 18, and he would have to wait 15 years before he could return triumphant from the Epsom Downs track to the tiny winner’s circle.

Incidentally that decade-and-a-half wait was something endured also by Sir Anthony McCoy, who had a similar barren spell in searching for his first Grand National.

In the meantime Dettori partnered several contenders who ultimately fell short – Tamure was second in 1995, Shantou was third in 1996, Cape Verdi was ninth as the 11-4 favourite in 1998, Dubai Millennium was also ninth as the 5-1 favourite in 1999, Tobougg was third in 2001, Snow Ridge was seventh as the 7-2 joint-favourite in 2004 and Dubawi was third in 2005.

Finally Authorized obliged in 2007 for trainer Peter Chapple-Hyam, winning by a wonderful five lengths as the 5-4 favourite and sweetening the sour relationship between Dettori and the race.

“It was a nightmare. Every time it came to the Derby it was a nightmare!” he said of the winless run.

“When I won in 2007 I was full of relief. Finally, it was the last piece of the jigsaw.

“It was a nightmare though, even more when I rode Authorized because he was a big favourite, it was a lot on me and it was a relief.

“Cape Verdi got beat, I rode Dubai Millennium, I rode loads of good ones that got beat.

“The point of the Derby is it’s only once a year – once it’s gone, it’s gone. At Ascot you’ve got 35 races, you’ve got the rest of the afternoon, but the Derby only comes once.”

Dettori would go on to win again in 2015, this time with the Gosden-trained Golden Horn, who struck as the 13-8 favourite and provided the rider with one of the most memorable days of his career.

“Golden Horn was a different thing because I really got to enjoy it, I was older and my kids were older,” he said.

“I didn’t have the pressure to try to win it for the first time either, so it was a lot more enjoyable. Probably my biggest thrill in one single race was that race.”

Though the racing industry has inevitably changed since Dettori first took to the track as a young man from Italy, he still considers the Derby the pinnacle of achievement in racing and credits it as the driving factor in the development of the thoroughbred breed.

“It’s the most important race, we have been breeding thoroughbreds for 350 years to win the Derby,” he said.

“For a jockey, when you start you want to win the Derby. Trainers, owners, breeders, the Derby is why we are breeding thoroughbreds, for this race.

“The tradition has been going for hundreds of years and it will be going for hundreds of years. It is the most important race.”
